Whether channel carries COMMANDS rather than VALUE data.

A channel is a command channel when its name ends in _cmd or contains the /cmd/ segment. Command channels are never deduplicated — re-issuing the same command is meaningful and must always be delivered. Mirrors raccoon::Channels::isCommandChannel in the C++ transport.

class raccoon_transport.channels.ProtocolChannels

Internal protocol channels used for reliable and retained delivery.

ACK = '__raccoon/ack'

RETAIN_REQUEST = '__raccoon/retain_request'

static reliable_channel(channel: str) → str

Return the wrapped channel name used by the reliability layer.
